[Dovecot] 1.1.3 vs 1.1.2 stability?
by Tomasz K Jarzynka 11 Sep '08

11 Sep '08

Hi, since I've numerous reports of segfaults/crashes/corruptions with Dovecot 1.1.3 with Sieve, I'd like to ask - is 1.1.3 an improvement over 1.1.2 or are there some acknowledged regressions and 1.1.4 is planned to fix that? I'd love to avoid figuring this on a live setup and hope to exploit other admins' courage ;P rgds, -- Tomasz Krzysztof Jarzynka / mob. +48 601 706 601 / HANDLE: TJ950-RIPE Network Information Systems Administrator / tomee(at)genesilico(d-o-t)pl Laboratory of Bioinformatics and Protein Engineering | www.genesilico.pl International Institute of Molecular and Cell Biology | www.iimcb.gov.pl

[Dovecot] NFS performance and 1.1.3 - what can you (unofficially) get away with?
by Jack Stewart 10 Sep '08

10 Sep '08

Hi, Does anyone have experience with bending the NFS recommendations to get better performance? The question is has anyone, with Maildir and the INDEX= on NFS (i.e. dovecot.index and dovecot.index.cache, set mail_nfs_index to no. If so, was it better to turn maildir_copy_preserve_filename to on or did it help to turn if off. The other question is did you play with turning off atime updates or changing the acmin* values? I know that the recommendation is do not do this. Fortunately Timo's screams won't reach my ears for another ten hours. I'm just interested if anyone has done this. You are most welcome to reply offline. I figure that the worst that can happen is that the dovecot.index.cache file will become corrupt, and dovecot will then rebuild it. As long as this doesn't happen all the time, it should not be a big deal. I'm guessing that this is less likely maildir_copy_preserve_filename turned on. My old (courier) servers is that I was able to get away with disabling atime updates and bumping up acmin* but then there was no central index to check. I admit that this is a nutty way to go since part of the whole point of 1.1.X is its NFS settings. Yet this is a place with some pretty nutty users. (i.e. 2+GB inboxes, 100K messages, one/minute connections, ...) ---Jack P.S. As a total aside people migrating from 1.0.X to 1.1.3 may wish to have to use a different INDEX directory in 1.1.3 than the one you used in 1.0.7. Doing this got rid of my index.cache and transaction log error messages. This may be why testing isn't showing anything. P.P.S. I've tried imapproxy for my webmail but it doesn't seem to have made much of a difference on the INDEX I/O.

[Dovecot] Question about subfolders
by Oliver Fromme 10 Sep '08

10 Sep '08

Hi, I've got an old dovecot installation (0.99.10.5) which is used as the back-end for a squirrelmail web mailer. Now I need to decide whether to update it to a newer version of dovecot or to switch to a different software. One feature that I really need is to be able to place messages and subfolders in a folder at the same time. This is with mbox format files (I can't use maildir). The old version of dovecot doesn't seem to support that, you can have either subfolders or messages in a folder, but not both. Does the current version 1.1.3 support it? Best regards Oliver PS: Please CC me because I'm not subscribed to the list. Thank you very much! -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.

[Dovecot] Panic: IMAP: Trying to allocate 2273345672 bytes
by Mark Zealey 10 Sep '08

10 Sep '08

Hi, we're running dovecot 1.1.2 (centos5 32-bit rpm from atrpms) havn't had any real issues with it, but today it looks like an index has become badly corrupted. We're seeing this in the logs every time we log in to a particular account: 2008-09-10T11:56:07+01:00 mail8 dovecot: Panic: IMAP(xxx): Trying to allocate 2273345672 bytes 2008-09-10T11:56:07+01:00 mail8 dovecot: IMAP(xxx): Raw backtrace: /usr/libexec/dovecot/imap [0x80d0310] -> /usr/libexec/dovecot/imap [0x80d036a] -> /usr/libexec/dovecot/imap [0x80cfc2c] -> /usr/libexec/dovecot/imap [0x80d966c] -> /usr/libexec/dovecot/imap [0x80ce750] -> /usr/libexec/dovecot/imap(buffer_create_dynamic+0x30) [0x80ce800] -> /usr/libexec/dovecot/imap(mail_index_sync_ext_intro+0x4d5) [0x80c0145] -> /usr/libexec/dovecot/imap(mail_index_sync_record+0x135) [0x80b11b5] -> /usr/libexec/dovecot/imap(mail_index_sync_map+0x269) [0x80b1d79] -> /usr/libexec/dovecot/imap(mail_index_map+0x38e) [0x80ab17e] -> /usr/libexec/dovecot/imap [0x80a825c] -> /usr/libexec/dovecot/imap(mail_index_open+0x1f4) [0x80a8554] -> /usr/libexec/dovecot/imap(index_storage_mailbox_open+0x79) [0x809ca39] -> /usr/libexec/dovecot/imap [0x806d339] -> /usr/libexec/dovecot/imap [0x806e1fa] -> /usr/libexec/dovecot/imap(mailbox_open+0x49) [0x80a09e9] -> /usr/libexec/dovecot/imap(cmd_select_full+0xa9) [0x805e459] -> /usr/libexec/dovecot/imap(cmd_select+0x19) [0x805e629] -> /usr/libexec/dovecot/imap [0x805fdec] -> /usr/libexec/dovecot/imap [0x805fe95] -> /usr/libexec/dovecot/imap [0x8060655] -> /usr/libexec/dovecot/imap(client_input+0x5e) [0x806086e] -> /usr/libexec/dovecot/imap(io_loop_handler_run+0x100) [0x80d7c80] -> /usr/libexec/dovecot/imap(io_loop_run+0x28) [0x80d6df8] -> /usr/libexec/dovecot/imap(main+0x4ac) [0x80683ec] -> /lib/libc.so.6(__libc_start_main+0xdc) [0x8c8dec] -> /usr/libexec/dovecot/imap [0x805a171] This account has about 12 mails in cur, nothing in new. Shortly before this corruption started, I saw entries like: 2008-09-10T10:20:15+01:00 mail9 dovecot: IMAP(xxx): /var/spool/mail/supplier_2/xxx/Maildir/dovecot-uidlist: Duplicate file entry at line 2: 1217249435.M999046P25889.mail7.atlas.pipex.net,W=2673:2,S (uid 1 -> 14) ... For all the mails in the cur directory. About our setup: These are on an nfs-mounted file system. It's shared between two computers and connections are randomly redirected to either box; so potentially it could be an nfs type corruption issue.

[Dovecot] Problems to sync
by Lincon Peretto 10 Sep '08

10 Sep '08

Dovecot 1.1.2 Good afternoon, I installed dovecot to work with Exim....my dovecot.conf is like this: #Protocolos suportados protocols = imap log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot-info.log #Desabilitar SSL ssl_disable = yes disable_plaintext_auth = no first_valid_gid = 0 mail_location = mailbox:/usr/home/%u/mail/:INBOX=/var/mail/%u mail_access_groups = mail protocol imap { login_executable = /usr/local/libexec/dovecot/imap-login mail_executable = /usr/local/libexec/dovecot/imap login_greeting_capability = yes } #Otimizacao dotlock_use_excl=yes maildir_copy_with_hardlinks=yes auth_verbose = yes auth_process_size = 256 auth_cache_ttl = 3600 auth default { mechanisms = plain user = root ssl_require_client_cert = no passdb pam { } userdb passwd { } } The problem is that I get to sync with INBOX, but I can't get to sync with the other files... I don't know if this line is correct: mail_location = mailbox:/usr/home/%u/mail/:INBOX=/var/mail/%u If I create a new file by the outlook, this file is created in the server normally..... If someone could help....thanks...

[Dovecot] Output of dovecot -a not sorted
by Charles Marcus 10 Sep '08

10 Sep '08

Hey Timo, I think I've asked you about this before, and I'm sure its not a big priority, but this is really a pain when trying to check default settings... The output of dovecot -a is huge, and the fact that it is not sorted alphabetically (nor is dovecot -n, but thats not as big of a problem, although I'd like to see that sorted as well for consistency) makes it really difficult to find certain settings you are looking for. Any chance of fixing this so it sorts the output alphabetically? Thanks, and thanks for dovecot! -- Best regards, Charles

[Dovecot] Data loss from removing dovecot.index* files?
by John Lightsey 10 Sep '08

10 Sep '08

Hi there, I've been rewriting the courier-dovecot-migrate script to handle dovecot->courier conversions in addition to courier->dovecot. One issue I've found is that when the courier->dovecot conversion is performed a second time (using --overwrite) and the dovecot-uidlist file is written again, Dovecot starts generating errors when accessing the maildir. The simple fix is to remove all of the dovecot.index* files so they are rebuilt when the maildir is scanned again. Is it safe to do this or is information stored in the index files that can't be rebuilt by Dovecot the next time it scans the maildir? J.D.

[Dovecot] Maildirsize file isn't updated after doing POP
by Nitass Sutaveephamochanon 09 Sep '08

09 Sep '08

Hello, I have a problem about updating Maildirsize file. It seems that the Maildirsize file is not updated after user does POP mail from his maildir. I do not want to use any quota limitation in Dovecot. I only want Dovevot to update the Maildirsize file after user retrieves his mail. The Maildirsize file is created by Postfix. Would it be possible to do like this? How can I configure it? Could you please advice me? The Dovecot version is 1.0.7. Thank you very much, Nitass

[Dovecot] No buffer space available
by Rick Romero 09 Sep '08

09 Sep '08

Hi, I'm running Dovecot 1.1.3 on FreeBSD 7.0. In the past couple days, I've been seeing errors like this: Sep 9 08:43:51 sysvol dovecot: pop3-login: socketpair() failed: No buffer space available Sep 9 08:43:51 sysvol dovecot: pop3-login: socket(default) failed: No buffer space available Sep 9 08:43:51 sysvol dovecot: pop3-login: Can't connect to auth server at default: No buffer space available Sep 9 08:25:15 sysvol dovecot: pop3-login: socketpair() failed: No buffer space available pop3-login: Can't connect to auth server at default: No buffer space available What ends up happening is that the port doesn't accept any new connections until there is enough buffer space. Yesterday, I saw it a LOT with POP3 and changed my config login processes: login_process_per_connection: no login_process_size: 256 login_processes_count: 6 This seemed to clear up the issues, but now it's occurring again this morning. I haven't had any of these since I made that change either.. So there's some progress... : Sep 8 12:53:40 sysvol dovecot: Temporary failure in creating login processes, slowing down for now TOP shows: Mem: 267M Active, 5558M Inact, 1637M Wired, 217M Cache, 214M Buf, 87M Free Swap: 4096M Total, 4096M Free At this time, there are 120 imap processes, 10 POP and 1 dovecot and 1 dovecot-auth pop and imap both have 6 login processes. It doesn't seem like a load issue, but obviously something is set too low or unavailable... It's fixed for a period of time when I restart dovecot. I did a netstat -m prior to restart, and after restart, and the only main difference was this line: Before: 11/414/425/12800 4k (page size) jumbo clusters in use (current/cache/total/max) After: 0/425/425/12800 4k (page size) jumbo clusters in use (current/cache/total/max) (After about 5 minutes 'current' went to 3) This machine also runs NFSd and MySQL. Any ideas? Thanks, Rick

[Dovecot] antispam plugin problem with dspam
by Harlan Stenn 09 Sep '08

09 Sep '08

I'm trying to use the dovecot antispam plugin with dspam. I'm running dovecot 1.1.2. Using thunderbird and IMAP, when I drag a spam message from the inbox into the SPAM folder, I get a popup saying "The current command did not succeed. The mail server responded: antispam signature not found. When I look at the message in the maildir folder, I see the dspam signature both in the header of the message and at the end of the body. What's a good way to debug this situation and figure things out? I'm not seeing anything in any log files, and I'm not seeing much in the way of debug capability in the dovecot antispam plugin.

[Dovecot] Sieve, and logging.
by Scott Sharkey 09 Sep '08

09 Sep '08

Hi All, Relatively new to Dovecot - converting from courier-imap. So far, I've got it working with virtual users (postfixadmin tables), and it seems to be working. I'm trying to get sieve working. It's not, so I tried turning up the logging, and putting it into a separate log file to get it out of the syslog for now. I can get the main dovecot to log, but I cannot get any log out of dovecot-deliver. I am thinking of replacing the dovecot-deliver with a shell script to see if it's even being called. Suggestions welcome! -Scott Logs and other relevant info follows: .# 1.1.2: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps pop3s managesieve ssl_ca_file: /etc/ssl/certs/ca.crt ssl_cert_file: /etc/ssl/certs/mail.linuxunlimited.com.crt ssl_key_file: /etc/ssl/private/mail.linuxunlimited.com.key login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no login_greeting_capability(managesieve): no first_valid_uid: 2000 mail_privileged_group: mail mail_location: maildir:/home/virtual/%d/%n/Maildir mail_debug: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve imap_client_workarounds(default): outlook-idle tb-extra-mailbox-sep imap_client_workarounds(imap): outlook-idle tb-extra-mailbox-sep imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls pop3_client_workarounds(managesieve): sieve_storage(default): sieve_storage(imap): sieve_storage(pop3): sieve_storage(managesieve): /home/virtual/%d/%n/sieve sieve(default): sieve(imap): sieve(pop3): sieve(managesieve): ~/.dovecot.sieve auth default: mechanisms: plain login user: nobody passdb: driver: pam passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: vmail plugin: sieve: /home/virtual/%d/%n/sieve ------------------------------------------------------------------------ # 1.1.2: /etc/dovecot/dovecot-sql.conf driver = mysql connect = host=127.0.0.1 dbname=mail user=postfixadmin password=xxxxxxxx default_pass_scheme = MD5-CRYPT password_query = SELECT password FROM mailbox WHERE username = '%u' AND active = 1 user_query = SELECT maildir, 2000 AS uid, 2000 AS gid FROM mailbox WHERE username = '%u' AND active = 1 ------------------------------------------------------------------------ Directories: /home: -rwxrwxrwx 1 root root 0 2008-09-07 23:06 dovecot-deliver.log drwxrwxrwx 2 root root 4096 2008-09-07 22:41 sieve drwxrwx--- 8 vmail vmail 4096 2008-08-27 22:26 virtual /home/sieve: -rw-r--r-- 1 root root 353 2008-09-07 22:41 global_rules.sieve -rw-r--r-- 1 root root 388 2008-09-07 23:22 global_rules.sievec /home/sieve/global_rules.sieve: require ["fileinto"]; require ["imapflags"]; if header :contains "Subject" "TestSPAM" { setflag "\\Seen"; fileinto "Junk"; stop; } ------------------------------------------------------------------------ Section of postfix main.cf virtual_transport = dovecot # limit dovecot service to one at a time... dovecot_destination_recipient_limit = 1 local_transport = virtual transport_maps = proxy:mysql:/etc/postfix/mysql_transport_map.cf ------------------------------------------------------------------------ Section of postfix master.cf # Dovecot Local Delivery Agent dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient} ------------------------------------------------------------------------ dovecot.log dovecot: 2008-09-07 23:02:49 Info: Dovecot v1.1.2 starting up dovecot: 2008-09-07 23:02:50 Info: auth-worker(default): mysql: Connected to 127.0.0.1 (mail) dovecot: 2008-09-07 23:03:25 Info: auth-worker(default): mysql: Connected to 127.0.0.1 (mail) dovecot: 2008-09-07 23:03:25 Info: auth-worker(default): mysql: Connected to 127.0.0.1 (mail) dovecot: 2008-09-07 23:03:27 Error: auth-worker(default): pam(ssharkey(a)linuxunlimited.com,24.192.79.39): pam_authenticate() failed: User not known to the underlying authentication module dovecot: 2008-09-07 23:03:27 Info: auth-worker(default): mysql: Connected to 127.0.0.1 (mail)

[Dovecot] cyrus2courier or cyrus2maildir.py, which to choose?
by Steinar Bang 09 Sep '08

09 Sep '08

What's the best utility to use to convert mail folders from a cyrus 2.2.13-10, on a debian 4.0 Etch system, to folders that can be used by dovecot? The http://wiki.dovecot.org/Migration/Cyrus page isn't too clear on what's the difference. cyrus2courier says "It should be able to preserve message UIDs, flags and 26 first keywords." cyrus2maildir.py says "preserves delivery timestamps and \Seen flags." But does that means that what cyrus2maildir.py preserves is in addition to what cyrus2courier preserves? Or is what cyrus2maildir preserves a subset of what cyrus2courier preserves? Thanx! - Steinar

[Dovecot] Error in Sieve + Dovecot 1.1.3
by Allan Cassaro 09 Sep '08

09 Sep '08

Hi, when I upgrade my dovecot to lastest version (from 1.1.1 to 1.1.3) and sieve plugins I discover a little problem in deliver (LDA) or in Sieve interface. With version 1.1.1 I have this in my dovecot.conf (and works fine) protocol lda { postmaster_address = root(a)mct.gov.br hostname = faraday.mct.gov.br mail_debug = no mail_plugins = cmusieve quota sieve_global_dir = /etc/dovecot/scriptssieve/ sieve = /home/%u/.dovecot.sieve } When I upgrade, the deliver/LDA stop to work and show me this message (in logs): deliver(acassaro): cmusieve: /home/%u/.dovecot.sieve doesn't exist So, when I change the "sieve" parameter, everything works fine again. protocol lda { postmaster_address = root(a)mct.gov.br hostname = faraday.mct.gov.br mail_debug = no mail_plugins = cmusieve quota sieve_global_dir = /etc/dovecot/scriptssieve/ sieve = ~/.dovecot.sieve } So, I don't know if this error is on LDA or Sieve patch (probably in sieve patch) Versions: dovecot-1.1.3 dovecot-sieve-1.1.5 dovecot-1.1-managesieve-0.10.3 dovecot-1.1.2-managesieve-0.10.3.diff Regards.

[Dovecot] Thunderbird, subscriptions, and upgrade to 1.1.3
by Jack Stewart 08 Sep '08

08 Sep '08

Hi, I've upgraded from 1.0.7 to 1.1.3. When I did this, my Thunderbird lost its brain and did not show some subscribed folders. squirrelmail also seemed to have issues. Applemail and mutt were fine. The configuration output is below. Hopefully this is just me and just random bizarreness. There wasn't a problem in 1.0.7 but I could have been caught in mid-upgrade. Thunderbird did not seem to update the subscription file (or at least I could not find the one it thought it was using). Any pointers are appreciated. Thanks in advance. ---Jack /opt/dovecot/sbin/dovecot -c /etc/dovecot.conf -n # 1.1.3: /etc/dovecot.conf Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 6144).

[Dovecot] zlib plugin nad moving mails, bug?
by Mateusz Kijowski 08 Sep '08

08 Sep '08

Hi, Recently I gzipped mails older than 30 days in our users' maildirs. I used find and gzip. Gzip added 'Z' at the end of the filename and everything seemed to work fine, users did not notice any difference in performance (yet :-), and I saved about 30% of our mail storage space. There seems to be a problem when moving gzipped messages from one folder to another though. Dovecot drops the Z flag, moved messages are not processed by the zlib plugin and email clients end up showing garbage. Is there something wrong with my config, or did I encounter a bug? dovecot -n follows: # 1.0.13: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log protocols: imap imaps pop3s ssl_ca_file: /etc/certs/certum-chain.crt ssl_cert_file: /etc/certs/wild.dfqs.pl.crt ssl_key_file: /etc/certs/wild.dfqs.pl.key ssl_cipher_list: ALL:!LOW:!MEDIUM login_dir: /var/run/dovecot/login login_executable(default): /usr/lib64/dovecot/imap-login login_executable(imap): /usr/lib64/dovecot/imap-login login_executable(pop3): /usr/lib64/dovecot/pop3-login login_greeting: imap.dfqs.pl ready. login_process_per_connection: no login_processes_count: 5 login_max_processes_count: 32 max_mail_processes: 4096 verbose_proctitle: yes mail_location: maildir:~/mail:INDEX=/var/lib/dovecot/indexes/%Ln mail_debug: yes maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: yes mail_executable(default): /usr/local/lib64/dovecot-post-login-imap.sh mail_executable(imap): /usr/local/lib64/dovecot-post-login-imap.sh mail_executable(pop3): /usr/local/lib64/dovecot-post-login-pop3.sh mail_plugins(default): imap_quota trash quota acl zlib mail_plugins(imap): imap_quota trash quota acl zlib mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib64/dovecot/plugins/imap mail_plugin_dir(imap): /usr/lib64/dovecot/plugins/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/plugins/pop3 mail_log_max_lines_per_sec: 0 imap_client_workarounds(default): outlook-idle tb-extra-mailbox-sep imap_client_workarounds(imap): outlook-idle tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh namespace: type: private separator: / inbox: yes namespace: type: public separator: / prefix: Public/ location: maildir:/var/vmail/Public:CONTROL=~/Public/control:INDEX=~/Public/index namespace: type: shared separator: / prefix: Shared/ location: maildir:/var/vmail/Shared:CONTROL=~/Shared/control:INDEX=~/Shared/index auth default: verbose: yes debug: yes worker_max_count: 512 passdb: driver: pam args: dovecot userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 user: root group: vmail master: path: /var/run/dovecot/auth-master mode: 432 user: root group: vmail plugin: quota: maildir:storage=12582912:ignore=Trash acl: vfile: trash: /etc/dovecot/dovecot-trash.conf

[Dovecot] v1.1.3 release candidate
by Timo Sirainen 08 Sep '08

08 Sep '08

I thought about making a release now, but I'll probably do some more fixes tomorrow, so here's a prerelease for everyone to test. :) If you see any bugs with this (old or new), please report. http://dovecot.org/tmp/dovecot-1.1.3-rc.tar.gz Important changes are: * mail_max_userip_connections limit no longer applies to master user logins. + login_log_format_elements: Added %k to show SSL protocol/cipher information. Not included by default. + imap/pop3-proxy: If auth_verbose=yes, log proxy login failures. + deliver: Added -s parameter to autosubscribe to autocreated mailboxes. - message parser fixes - hopefully fixes an infinite looping problem - SORT: One more assert-crashfix when renumbering index sort IDs. - mbox: Saving may have truncated the mail being saved - mbox: Several other bugfixes - mail_full_filesystem_access=yes was broken when listing mailboxes (it still is with maildir++ layout). - maildirlock utility was somewhat broken - zlib plugin: bzip2 support was somewhat broken - NFS: Make sure writing to files via output streams don't assert-crash when write() returns only partial success.

[Dovecot] Error starting dovecot
by Diego Ledesma 08 Sep '08

08 Sep '08

Hello, I have a linux system (Ubuntu 7.04 server edition) running Postfix 2.3.8 Today i installed Dovecot through apt-get (got version 1.0.rc17 installed) and configured it to do sasl auth only, (i already have other pop3,smtp and imap servers running) following the howto's at dovecot.org The thing is that if i try to start dovecot or run dovecot -n i get this message: Error: Can't use mail executable /usr/lib/dovecot/imap: No such file or directory That directory does not exist but why should it if i don't want to run dovecot as imap? I only installed dovecot-common package. Also, i setted protocols to "none". Does anyone know why i get that error message? One last comment. Before installing dovecot on the production mail server i installed it on my laptop's linux (Ubuntu 8.04 LTS) for testing purposes. The testing mail server runs Postfix 2.5.1 and Dovecot 1.0.10 and in this case Dovecot runs fine (the /usr/lib/dovecot/imap directory does also not exist and dovecot.conf is configured exactly on both servers). This are the uncommented parts of dovecot.conf #Only use dovecot-auth protocols = none disable_plaintext_auth = no log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:~/Maildir mail_privileged_group = mail protocol imap { } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } auth default { mechanisms = plain login passdb passwd-file { args = /etc/passwd.dovecot } passdb pam { } userdb passwd { } user = root socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } dict { } plugin { } ---- Any help is greatly appreciated.

[Dovecot] Cosmetic issue with dots in Maildir folder names
by Holger Weiss 08 Sep '08

08 Sep '08

Just a minor cosmetic issue: We use the listescape plugin in order to support "." characters in Maildir++ folder names, and in at least the following case, the escaped representation of the dot character ("\2e") won't be translated back to a "." in messages for the IMAP client: | 1 SELECT non.existent | 1 NO Mailbox doesn't exist: non\2eexistent However, SELECTing an existing folder whose name includes a dot works fine, and it also works in other cases, e.g.: | 2 CREATE does.exist | 2 OK Create completed. | 3 LIST "" does.exist | * LIST (\HasNoChildren) "/" does.exist | 3 OK List completed. This is with Dovecot 1.1.3; we use "separator = /" and we've defined REAL_SEP to '.' and VIRTUAL_SEP to '/' in the plugin. Holger

[Dovecot] ACL plugin: k permission and sub-subfolders
by Heiko Schlichting 07 Sep '08

07 Sep '08

Hi, I'm trying to disallow the creating of subfolders for some special folder for all users. Using ACL plugin for this seems to work at first glance but is not a full solution or is buggy as it allows the creation of sub-subfolders. I'm using the following ACL and namespace separator is "/": $ cat folder owner lrwstie Note: no "k" permission ("k" = create = Mailboxes can be created under this mailbox) Seems to work: a001 create "folder/subfolder" a001 NO Permission denied But: a002 create "folder/subfolder/subsubfolder" a002 OK Create completed. This is unexpected. Creating a subfolder is not allowed but a sub-subfolder is permitted? If this is intentional, the description in the wiki should mention this.

[Dovecot] v1.1.3 released
by Timo Sirainen 05 Sep '08

05 Sep '08

http://dovecot.org/releases/1.1/dovecot-1.1.3.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.3.tar.gz.sig This fixes several mbox problems previous v1.1 releases have had. * mail_max_userip_connections limit no longer applies to master user logins. + login_log_format_elements: Added %k to show SSL protocol/cipher information. Not included by default. + imap/pop3-proxy: If auth_verbose=yes, log proxy login failures. + deliver: Added -s parameter to autosubscribe to autocreated mailboxes. - message parser fixes - hopefully fixes an infinite looping problem - SORT: One more assert-crashfix when renumbering index sort IDs. - mbox: Saving may have truncated the mail being saved - mbox: Several other bugfixes - mail_full_filesystem_access=yes was broken when listing mailboxes (it still is with maildir++ layout). - maildirlock utility was somewhat broken - zlib plugin: bzip2 support was somewhat broken - NFS: Make sure writing to files via output streams don't assert-crash when write() returns only partial success.

[Dovecot] Time Moved Backwards Error Keeps Happening
by JackyC＠umac.mo 05 Sep '08

05 Sep '08

Hi all, I am running dovecot version 1.1.1 (dovecot --version) and keeps to have time moved backwards problem. I first found dovecot dead without obvious error message, but see the following when restart dovecot service by # service dovecot restart >Stopping Dovecot Imap: [FAILED] >Starting Dovecot Imap: Warning: Last died with error (see error log for more information): Time just moved backwards by 4398 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards [ OK ] I followed the above official wiki link and apply the ntpd service for adjusting the server timestamp. After running the ntpd service, I found the server timestamp drift is only 14.333 microsecond, I think which would be reasonable. But I still get the captioned error. Does anyone have the same experience? BTW, I couldn't find the error log message even I confirmed the info, error and debug log file by visiting this wiki document http://wiki.dovecot.org/Logging, does it really not log at the log file? I can just keep monitoring the log and use the following command to determine whether dovecot is running or not. # service dovecot status Thank you very much! Yours Sincerely, Jacky, Hoi Kei Chan,

[Dovecot] Integrating Dovecot SASL into Postfix
by Diego Ledesma 04 Sep '08

04 Sep '08

Hello. I have a linux system (Ubuntu 7.04 server edition) running as a mail server with Postfix. SMTP authentication is not configured so users have to be connected to the lan to download/send mails. I´m considering on enabling SMTP authentication and i have heard that by installing Dovecot i can do this pretty straight forward. First of all, some details about how the mail server is configured: - Running Linux OS Ubuntu 7.04 - Currently running Postfix version 2.3.8 - No virtual users or domains . Every system user has a mail account (to create a new mail account i have to create a new system user. I belive this is called PAM, right?). According to postfix´s website the version of postfix i have supports Dovecot 1.0 SASL protocol. What would happen if i try to install Dovecot through apt-get?. I mean, i most definitely get a version of Dovecot above 1.0. Would my postfix still support it?. Before posting this i have posted on the postifx mailing list and they have to told me that after installing Dovecot i don´t need to configure it as a pop/iamp server. How would i accomplish this?. Any help is greatly appreciated. Thanks. Diego.

[Dovecot] Sieve problem with 1.1.2
by justin＠ma3x.net 04 Sep '08

04 Sep '08

Hello, I am new here, so excuse me if i am asking something already asked. I am using dovecot 1.1.2 along with postfix 2.6 and a pgsql backend. So far everything is great, until i wanted to try out the sieve implementation. I am using dovecot for deliver and i have set global_script_path = /home/vmail/globalsieverc The script IS working until a given user defines his own sieve script ( for example ) : require ["fileinto"]; # Move mail from my gmail account to gmail folder if header :contains "From" ["xxxxx(a)gmail.com"] { fileinto "gmail"; } This ( or any other script for all i know ) breaks up the global one, and it stops working. The global script looks like this : require ["fileinto"]; # Move spam to spam folder if header :contains "X-Spam-Flag" ["YES"] { fileinto "spam"; stop; } Am i missing something, or this is the desired behaviour ?

[Dovecot] Dovecot ManageSieve + ingo or avelsieve
by Olivier Dijoux 03 Sep '08

03 Sep '08

Hi, does anyone got Dovecot ManageSieve and Horde/Ingo working together ? i'm running Dovecot 1.1.2 with managesieve patch (dovecot-1.1.2-managesieve-0.10.3.diff) following intructions at http://wiki.dovecot.org/ManageSieve now my Dovecot have ManageSieve available :-) I've setup Horde/Ingo (ingo-h3-1.1.5-1.el5) when I specify some new filtering rules in Ingo, they are successfully uploaded using managesieve to Dovecot server and seems to be working. But when I logout/login back to Ingo, no rules are visible. Previously defined rules are still working with dovecot (because the ingo.sieve which links to .dovecot.sieve contains them), but Ingo is ignoring them at all. also my Dovecot managesieve setup is working well with avelsieve-1.9.4 plugin for Squirrelmail, but not with latest avelsieve-1.9.7 (see http://article.gmane.org/gmane.mail.squirrelmail.plugins/13818 ) : in avelsieve-1.9.7 same as Ingo, it forget rules ! any suggestion ? Ingo backends.php is : ---- $backends['sieve'] = array( 'driver' => 'timsieved', 'preferred' => 'localhost', 'hordeauth' => true, 'params' => array( // Hostname of the timsieved server 'hostspec' => 'localhost', // Login type of the server 'logintype' => 'PLAIN', // Enable/disable TLS encryption 'usetls' => false, // Port number of the timsieved server 'port' => 2000, // Name of the sieve script 'scriptname' => 'ingo', ), 'script' => 'sieve', 'scriptparams' => array() ); ---- PS : any ManageSieve patch for Dovecot v1.1.3 ? thanks -- Olivier

[Dovecot] checkpassword migration script in Python
by Dan Udey 03 Sep '08

03 Sep '08

Hey all, First post to the list, so here goes, hope I don't break any rules (I didn't see any rules about not being overly verbose) I spent a long time looking for anything that would help me migrate from our old IMAP server to our new one without a lot of client-side fuss, multiple e-mail accounts, and so on. I find that a lot of our users get confused by having two 'inboxes' in Outlook (one local, unused, and one IMAP), so I figured the easier I could make it, the better. I figured there must be some way to do what I was looking for, but I couldn't find it, so I hacked up a little something to do the job. As the saying goes, it's nasty, brutish, and short, but in my tests it's done everything I needed it to. The problem: Our old mail system is hosted by another company, outsourced before I was hired, so I don't have access to the old user/ passwd database, nor to their e-mail store; thus, I cannot do a clean, simple migration by upgrading in-place as I have done on other servers. The solution IMAP authentication proxying. The idea is that I don't need to know the password, because the user's mail client knows the password, so all I need is for it to tell me, and then I can create their user. That is what this script is for. To use, set up your authentication backend (passdb) first, and then after that section, add a 'passdb checkpassword' section containing this script. Thus, the following will happen. 1. Valid users who log into your system will be authenticated as you would expect. 2. Users who could not be authenticated will fall through to the checkpassword section 3. Checkpassword will look for the user in the password database; if they exist, it is assumed that it is a valid user, but incorrect password, and checkpassword fails the user as well. 4. If the user is not currently in the database, it will initiate an IMAP4 connection to the remote host specified. If it succeeds in logging in to the remote host, then we assume that the user is a valid user and can be migrated to the local server. They are added to the database, along with their password. It then **fails the user's login regardless** 5. It /logs the username and password into the database/ so that another process can use that information to migrate their e-mail over to the new server (not yet implemented). 6. If the IMAP connection fails, the login is failed as well, and dovecot continues as normal until it has exhausted all other passdb backends. Interested? A few things to note about the script: 1. It's a brutal hack. Really, ugly stuff. However, it gets the job done, if your system is similar enough to mine. 2. It only works on MySQL. I only use MySQL in our system, so there's no point for me to add other DBs, nor any way to test. 3. It doesn't support remote servers using SSL. Our current system doesn't use it, so again, it's hard to test. 4. It does not currently migrate mailboxes. I'm working on this (see below). 5. If your schema is at all different from mine, you will likely have to rewrite all of the SQL. There's not much I can do about this. 6. If your backend database doesn't use MySQL, you're largely boned. Exception: rewrite add_user() to do whatever you need to do to add users to your system. 7. The script will **ALWAYS RETURN A FAILED LOGIN TO DOVECOT**. This is because there are too many variables on every configuration, and writing code for all of them is absurd. This way, the user's first login will always fail, and their second login will always succeed. If you want to avoid this, place your normal passdb authentication **both before and after this checkpassword section**. That way, it will check once, fail, pass to checkpassword, and then check again, success. TODO: 1. Make it not ugly. Break more junk off into functions (e.g. IMAP verification) 2. Send the user an e-mail ('Welcome to the server, sorry your mail is gone, we'll fix that soon') 3. Spawn another process to run imapsync in the background to migrate the user's old mailboxes over. This would be very site-dependent, as there are a lot of variables. It might be best done as a cronjob that polls the database every however often (1 minute? 2 minutes?) or a daemon that sits in the background watching the db for changes, or even accepting the data directly. 4. Stop being so verbose in my first postings to mailing lists. 5. Lots of other things. URLS Blah blah blah where's the code. Here you go. Pretty syntax-highlighted version for browsing before you download, in case I'm an evil hacker: http://cdslash.net/temp/python/checkpassword.py Ugly monochrome version for downloading so you don't get line numbers in your junk: http://cdslash.net/temp/python/checkpassword.raw Questions, comments? I probably won't be on the list very long, so if you want to ask something or have a suggestion, feel free to let me know by e-mail at the address listed in the file's license notification. Alternately, find me on Freenode, occasionally in #dovecot or always in #macosx, as Darien, or some variant thereof.

[Dovecot] authorizing users
by Wade Smart 03 Sep '08

03 Sep '08

Im trying to clarify if I understand correctly about authorizing users. "The simplest login method is sending the user login info in plain text and allowing access only to users that already have UNIX access (ie. in /etc/passwd) to the machine dovecot is running on." Im using fetchmail postfix dovecot on my own personal computer to get my mail from two servers. What Im wanting to understand is, is this saying that since I am already a user on my own system, that by using /etc/passwd that I would use my username and password in say thunderbird to login to dovecot to get my mail?

It's possible this is a 32/64-bit incompatibility issue (imap is a 64- bit program for me; mail might have been delivered by a 32-bit deliver or previously read by a 32-bit imap) but more likely the dovecot* files are just hosed in some way. I can provide more information if you ask soon, but I can't keep this server broken for too long.

[Dovecot] Authentication problems
by Rodti MacLeary 02 Sep '08

02 Sep '08

Hi there, I'm in a bit of a dilemma and wonder if anyone can help. Over the weekend I bought a new dedicated server and moved my mail/web over to it. I'd used the Sarge[1] tutorial at workaround.org for the old server and as I'd wanted to move to Dovecot for a while I decided to use their Etch[2] tutorial for the new one. For the most part everything's working nicely, but I seem to be having problems with (mostly non-SSL) SMTP authentication. In this install Postfix passes SASL authentication to Dovecot. For most clients using SSL this works fine, but as soon as SSL is off it fails. This is despite having disable_plaintext_auth set to 'no'. Furthermore it appears that some clients w/SSL are also failing. Outlook being the major culprit. I'm completely stumped. I've pasted a copy of the output from dovecot -n below. Thanks in advance!

[Dovecot] "pam_start() failed: system error" with dovecot 1.1.2, cause unknown
by Adam McDougall 02 Sep '08

02 Sep '08

I would guess this is unlikely to be dovecot's fault, but I'm wondering if anyone has any ideas of what might have happened based on the evidence. My best guess is some kind of resource limit was reached but I don't see any evidence in the logs, and the condition is now gone. Suddenly this morning, one (and only one) of my dovecot servers decided to start failing all logins since 08:25:04 until we restarted dovecot, at which point they were working fine. The number of imap-login processes was under the limit, but there were some obvious PAM errors at the time. My account could still ssh to the system so I don't think it was a problem general authentication, and NIS on other systems was working fine. No one was logged into that server at the time the problems occurred, and I don't think anything happened to the actual pam libraries to make them missing since dovecot worked after a restart. I should have used other means to prevent people from using that dovecot instance rather than stopping it, and I'll do so if it happens again in hopes of further debugging. /var/log/maillog: Sep 2 08:25:01 hill dovecot: imap-login: Login: user=<userA>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Sep 2 08:25:01 hill dovecot: IMAP(userA): Disconnected: Logged out bytes=127/568 Sep 2 08:25:01 hill dovecot: imap-login: Login: user=<userA>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Sep 2 08:25:01 hill dovecot: IMAP(userA): Disconnected: Logged out bytes=282/9641 Sep 2 08:25:04 hill dovecot: imap-login: Login: user=<userA>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Sep 2 08:25:04 hill dovecot: IMAP(userA): Disconnected: Logged out bytes=46/543 ***problem started here Sep 2 08:25:04 hill dovecot: auth-worker(default): pam(userA,127.0.0.1): pam_start() failed: system error Sep 2 08:25:04 hill dovecot: auth-worker(default): pam(userB,35.9.37.164): pam_start() failed: system error Sep 2 08:25:05 hill dovecot: auth-worker(default): pam(userC,35.9.37.164): pam_start() failed: system error Sep 2 08:25:06 hill dovecot: imap-login: Aborted login (auth failed, 1 attempts): user=<userB>, method=PLAIN, rip=35.9.37.164, lip=35.9.37.190, TLS Sep 2 08:25:06 hill dovecot: imap-login: Aborted login (auth failed, 1 attempts): user=<userA>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Sep 2 08:25:07 hill dovecot: imap-login: Aborted login (auth failed, 1 attempts): user=<userC>, method=PLAIN, rip=35.9.37.164, lip=35.9.37.190, TLS ..... /var/log/messages: Sep 2 08:25:04 hill dovecot-auth: in openpam_load_module(): no pam_permit.so found Sep 2 08:25:04 hill dovecot-auth: in openpam_load_module(): no pam_login_access.so found Sep 2 08:25:05 hill dovecot-auth: in openpam_load_module(): no pam_nologin.so found Sep 2 08:25:10 hill dovecot-auth: in openpam_load_module(): no pam_unix.so found Sep 2 08:25:11 hill dovecot-auth: in openpam_load_module(): no pam_unix.so found Sep 2 08:25:20 hill dovecot-auth: in openpam_load_module(): no pam_opieaccess.so found Sep 2 08:25:20 hill dovecot-auth: in openpam_load_module(): no pam_opie.so found Sep 2 08:25:51 hill kernel: Sep 2 08:25:51 hill last message repeated 12 times Sep 2 08:27:52 hill kernel: Sep 2 08:27:52 hill last message repeated 37 times Sep 2 08:38:01 hill kernel: Sep 2 08:38:01 hill last message repeated 144 times Sep 2 08:48:06 hill kernel: Sep 2 08:48:06 hill last message repeated 129 times Sep 2 08:53:36 hill kernel: Sep 2 08:52:51 hill last message repeated 51 times

[Dovecot] Bad file descriptor with maildir and bzip2 files
by Chris Burton 02 Sep '08

02 Sep '08

Hi, I'm using the zlib plugin with dovecot 1.1.2 (on Centos 4.5, x86, ext3) and some bzip2 (version 1.0.2) compressed mail files are causing the following error to show in the logs when I click on the folder in outlook express. Aug 27 11:39:15 server-2 dovecot: IMAP(marchive): fstat(maildir) failed: Bad file descriptor Aug 27 11:39:17 Info: IMAP(marchive): Loading modules from directory: /usr/local/lib/dovecot/imap/ Aug 27 11:39:17 Info: IMAP(marchive): Module loaded: /usr/local/lib/dovecot/imap//lib20_zlib_plugin.so Aug 27 11:39:17 Info: IMAP(marchive): Effective uid=606, gid=609, home=/home/marchive Aug 27 11:39:17 Info: IMAP(marchive): maildir: data=/var/spool/maildir/marchive Aug 27 11:39:17 Info: IMAP(marchive): maildir++: root=/var/spool/maildir/marchive, index=, control=, inbox=/var/spool/maildir/marchive Aug 27 11:39:18 Info: IMAP(marchive): Disconnected: Internal error occurred.
